A regular expression (shortened as regex or regexp; [1] sometimes referred to as rational expression [2] [3]) is a sequence of characters that specifies a search pattern in text. Python supports multiple ways to format text strings. These include %-formatting [1], str.format () [2], and string.Template [3]. Each of these methods have their advantages, but in addition have disadvantages that make them cumbersome to use in practice. This PEP proposed to add a new string formatting mechanism: Literal String Interpolation. Regex.
